THROTTLE HEATER.

'Application filed August 26, 1920. Serial No. 406,068.

To all whom it may concern.'

Be it known that I, PAUL DANIEL, citizen ofthe Republic of France, and resident of Boundbrook, in the county of Middlesex and State ot' New Jersey, have invented certain new and useful Improve ments in a Throttle Heater, of which the following is a specification. p

This invention relates-to a throttle heater by means of which they gasoline or other liquid fuel discharged from the spray nozzle of any carbureter is quickly vaporized, to secure the easy starting and efficient op eration of the engine with which the heater is employed.` The organization of the invention comprises a casing which is substituted for the buttery valve of the carbureter of the engine. The said casing with its cover is of a width not greater than the diameter of the hub of the butterfly Avalve of' the carbureter for which it is substituted. A resistance coil in the casing is imbedded in non-'electric conducting material, but which will conduct heat.` The said material holds the coil firmly in place. An electric current is transmitted to the coil which is thereby heated. The heat of the coil is transmitted to the walls of the casing and cover which in turn heats the mixture inthe c'arbureter as it flows into the manifold of the engine. When the throttle heater is placed in its closed position, the heat generated in the carbureter will be confined therein and not escape into the manifold.

In "the accompanying drawings Fig. l represents a part vertical axial ,sectiony and elevation of a carhureter with the heater shown in full lines in its closed position and iny dotted lines .in its open position;

` Fig. 2 shows a section of Fig. l on the line 2, 2 with the throttle heater swung to its j open position; Fig. 3 is an enlarged section of the throttle heater onthe line 3, 3 of F ig.

3; Fig. 4 shows an enlarged front view lof the main portion of the heater -withits cover Vand Fig.5 represents a section of Fig. 2 somewhat reduced on the `line 5, 5.

A carbureter is designated in its entirety by the letter A and has connected thereto the bonnet B with the discharge barrel 20 having the upper fiange 2l. An annular projection 22 is formed with the flange 21. An upper barrel 25 has formed at its upper `endv` the flange 26 and at its lower end the flange 27 with the annularl recess 28 that locks with `20 and 25 are formed the the barrel'20 below the the annular 32 at their lower ends are/in threaded engagement with the cap B and at their upper ends have formed therewith the flanges At the junction of the barrels journal bearings 34 and 35 one portion of veach journal bearing is connectedto the barrel 20 and its other portion is connected to the barrel 25. Upon the flange 26 is located the flange `36 of a manifold 37 of a hyd-ro carbon Nuts 38 clamp the flange 36 to the and the joint between the barrels engine. fange 26 2O and 25 is sealed by means of the boltsV 32 and their flanges 33.

The throttle heater .designated in its entirety by the letter D, comprises theoval casing having the main wall 42 with the end circumferential walls 43 and 44 that incline respectively to the main wall 42. The walls 43 and 44 join with the portions projection 22. Standing boltsV 45 that are perpendicular to the wall 42."

The walls ol the said casing engage with the walls" of the barrels 20 and 25 when in their inclined closed position, as shown in Fig. l. Fins 46 extend from the outer face of the wall 42. A snap cover 47 with the fins 48 similaito the fins 46 is detachably locked to the oval casing. The heater D with its cover functions as a butterfly valve for the carbureter and closes the passage in the barrels 2() `and 25 when in its closed position. Tubular ytrunnions 52 and 53 are formed with the casing of the heater D and are respectively supported in the journal bearthreaded end 57 clamp between them one Lend of' the spring contact electric bar 60.

A lock nut 59 locks with the nut 58. An interiorly threaded boss 63 is formed with journal bearing 34.

A threaded plug 64 of electric insulating `material with .the head 65 is in threaded engagement with the boss 63. with. the head 67 extends axially through the `plug 64. The screw 66 extends through an opening in the lower end of the contact bar 60. A pair of nuts 68 and 69 clamp the lower end of the bar 60 in place. A bind ing post cap 70 is in threaded engagement with the screw 66. The snap jaws 71. 72

A screw 66 S33, the casing ot the heater 16 and its fins L.t7 into the iliuel oi" ot a wire (not shown) Afor electric current detachably lock with the cap 70.

In the heater D is located a resistance coil designated in its entirety by the letter E and is shown with the end members 7 4l and 75. The member 74C extends through an opening in the rod 5G. A separator sleeve 76 encircles the rod 56 and bears between the member 7 il et the coil E and the accompanying end tace or' the plug 5a, whereby the member 7 fl is securely clanfiped in place. ln the trunnion 53 is located the tubular nut 7 8 with, the button head 79. A rod 8O is in threaded engagement with the nut 78. rllhe member 75 ol the coil .E extends through an opening in the rod and said member bears against the adjacent inner 'tace ot the wall ot the heater D and is thereby kept in place. The connection oit the members 7d and 75 ot the coil E with the rods 56 and SO allows the easy detachment of said coil 'for repairs or replacement. The usual operating` arm 82 ot the butterfly valve ot the carbureter is fastened to the trunnion 53. A heat conducting and electric n on-conducting material S3 in the heater D has the coil .lil embedded therein. The material 8B is introduced in the heater D in liquid or plastic term, and upon solidi'fying encloses the coil ll and prevents it vibrating.

In the operation ot the throttle heater electic current is iturnished by the wire et the snap jaws 7l, 72. The electric current flows through the contact bar (it), thence through the rod 5G and then into the heating coil E after which it is grounded. rllhe heat ot the coil E is transmitted by the material D and its 'tins 45, the cover gasoline ,mixture as it Viiowi troni the car- `Jureter. rlhe heater transmits the heat units et the resistance coil Fi to the 'tuel mixture at a temperature that is lmuch less than the temperature ot said coil. This prevei'its preignition in the manifold 37. The coil Vlil is securely embedded in the material Sil and is prevented entering` the nninitold in nase ot accidental breakage.

This torni ot the throttle heater is pret erably used tor engines o'lf large sir/.e and. which use a low grade ot fuel or gasoline. By means of this tform ot heater the heat from the coil E is directed both into the carburetor and into the manifold ot the engine.

In the medication shown in Fig. 5 the heater D is shown with its tins Lie, trunnions 53 and 54, heating coil E, electric insulating material S3, and their appurtenances as already described. The snap cover 47 in this modification is devoid ot tins and a sheet of asbestos 86 is placed over the in sulating material 83. This modification is used for small engines that use a high grade ot gasoline and with it the heat generated in the coil E is to a great extent directed into the lower portion ot the carburetor.
